Creating Custom WordPress REST API Endpoints
WordPress REST API provides developers with a way to interact with WordPress sites programmatically. By default, WordPress comes with several built-in REST API endpoints for posts, pages, users, and more. However, there may be cases where you need to create custom endpoints to fetch or manipulate data specific to your plugin or theme.
To create custom REST API endpoints in WordPress, you need to use the register_rest_route function. This function allows you to define a new route for your endpoint, specify the HTTP method it responds to, and define the callback function that handles the request.
function flashify_custom_endpoint() {
register_rest_route( 'flashify/v1', '/custom', array(
'methods' => 'GET',
'callback' => 'flashify_custom_endpoint_callback',
) );
}
add_action( 'rest_api_init', 'flashify_custom_endpoint' );
function flashify_custom_endpoint_callback( $request ) {
// Your custom endpoint logic goes here
}
In the code example above, we have defined a custom REST API endpoint at example.com/wp-json/flashify/v1/custom using the register_rest_route function. The endpoint responds to GET requests and calls the flashify_custom_endpoint_callback function to handle the request.
When creating custom REST API endpoints, it is essential to follow WordPress coding standards and best practices. Make sure to sanitize and validate input data, handle errors gracefully, and use proper authentication methods if needed.
Custom REST API endpoints can be used to fetch data from external sources, perform complex queries, or integrate with third-party services. By leveraging the power of the WordPress REST API, developers can extend the functionality of their plugins and themes, providing users with more dynamic and interactive experiences.
